Description
Technical field
The present invention is relevant to a kind of display packing and related system, espespecially a kind of method and display system that shows simultaneously bidimensional image and 3-dimensional image.
Background technology
Compared to conventional two-dimensional (two-dimensi onal, 2D) plane Display Technique, three-dimensional (three-dimensional, 3D) stereo display technique can provide more lively 3-dimensional image, and therefore how being issued to three-dimensional stereoscopic visual at existing two-dimentional display environment has become one of important directions of now Display Technique development.Present stereo display technique mainly contains disparity barrier (parallax barrier) technology of using, and uses the depth of field of Multilayer panel to merge (depth fused) technology.
The style of shooting of the three-dimensional video signal of conventional three-dimensional or image is to utilize many video cameras to take, and the video signal that obtains or capacity image are quite large, under limited frequency range and be unfavorable for transfer of data and preservation.Therefore, ATTEST proposes a kind of video-signal system of 3D/2D pattern compatibility, it uses the depth of field integration technology of Multilayer panel, only need utilize single video camera to obtain the planar coloured image of a specific stereoscopic picture plane and the corresponding depth of field (depth) data, afterwards at display end recycling degree of depth drawing image algorithm (depth-image-based rendering, DIBR) rebuild original stereoscopic picture plane, therefore can significantly increase data transmission efficiency.
Please refer to Fig. 1 and Fig. 2, Fig. 1 is the functional block diagram of the display system 100 of available technology adopting depth of field integration technology, and the schematic diagram of Fig. 2 when being display system 100 running of prior art.Display system 100 comprises a header board 10F, a rear plate 10B, a data converting circuit 20, and a data decode circuitry 30.In order between 2D pattern and 3D pattern, to switch, display system 100 is after receiving the bidimensional image data 2D that is relevant to the specific three dimensional image frame depth of field data Z corresponding with it, data converting circuit 20 can be according at present digital video broadcasting (digital video broadcasting, DVB) standard is converted to bidimensional image data 2D and meets the at present form (for example MPEG-2) of existing flat-panel screens, and with depth of field data Z boil down to specific format (for example MPEG-4 or AVC) in order to transfer of data.After bidimensional image data 2D after will compressing and depth of field data Z were sent to display end, data decode circuitry 30 can be obtained corresponding header board image DATA according to the DIBR algorithm
